Textbook Question
Chapter 1, Problem 1.13LM
Suppose you’re given a data set that classifies each sample unit into one of four categories: A, B, C, or D. You plan to create a computer database consisting of these data, and you decide to code the data as A = 1, B = 2, C = 3, and D = 4. Are the data consisting of the classifications A, B, C, and D qualitative or quantitative? After the data are input as 1, 2, 3, or 4, are they qualitative or quantitative? Explain your answers.

You own the only pharmacy in the small town of Jackson City, which has 40,000 residents. You would like to get a sense of what the local demand is for seasonal allergy medicine so you can determine how many packages to keep in stock and what price to charge. You conduct a survey of four residents of Jackson City, asking them about the quantity of allergy medicine they would buy each allergy season at various prices. Their responses are shown in the accompanying table. Estimate and graph the demand for the entire town of Jackson City.

If you could please answer this specifically I would appreciate it.arrow_forwardOn many issues, the United Nations General Assembly (UNGA) decides matters through simple majority vote. Suppose the UNGA is voting on the amount of aid to send to a country following a natural disaster (e.g., the 2004 Indian Ocean tsunami; the 2010 Haiti earthquake). This amount can be plotted along a single dimension, which, for simplicity, we will allow to range between 0 and 1: For simplicity, assume there are only seven countries in the UNGA: A, B, C, D, E, F, and G. Each country has an ideal point, indicated in the parentheses below each country’s letter (i.e., A’s ideal point is at .05, E’s ideal point is at .75, etc.). Assume the countries have single-peaked preferences (i.e., countries want policy to be as close as possible to their ideal points) and that the voting rule is simple majority (i.e., each country gets one vote, and the policy supported by a majority wins).

(b) Write a sentence that explains the result in part (a) in the context of this problem. For every additional drill sold, the price per drill (in cents) decreases by cent(s).

- Salop circle spatial model Imagine a circular city with a circumference of 50 miles. A total of 500 people live around the city, all of whom are evenly spaced. It costs any person 10 cents per mile to travel. Every one of these people needs to have exactly one meal prepared. The cost of preparing meals is given by C(g) = 10 + 0.5q where q is the number of meals prepared at any restaurant. (Hint: Define one unit of distance as 50 miles if that makes the problem easier.) a.If you were interested in the efficient way to feed the population, how many restaurants would you build?

In what sense is this model one of monopolistic competition?arrow_forwardGreenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. In this part, you will draw two pie graphs. A pie graph is used to show how a certain quantity has been divided into several parts, as well as to show the comparisons among these parts. 1. The data table below shows the total U.S. greenhouse gas emissions by economic sector in 2013, in million metric tons of CO2. On the pie graph provided, complete the graph to show the percent of greenhouse gas emissions for each economic sector. Label each section of the pie graph with its economic sector. The percent for "Agriculture" has been drawn and labeled for you.
